A high-power system instrument has been unveiled by Keithley Instruments, Inc. The Model 2657A adds a high-voltage capacity to the company’s existing range of 
high-speed, precision source measurement units. It enable characterisation of power semiconductor devices and materials. With a built-in 3,000V, 180W source, it is claimed to be able to source up to five times as much power to a device under test as other similar instruments.
An in-built precision, high-speed 6-1/2-digit measurement engine enables 1fA (femtoamp) current measurement resolution to support the low-leakage requirements of next-generation power semiconductor devices.
The unit is optimised for high-voltage applications such as testing power semiconductor devices, including diodes, FETs, and IGBTs, as well as characterising newer materials such as gallium nitride (GaN), silicon carbide (SiC), and other compound semiconductor materials and devices. It is also useful for characterising high-speed transients and performing breakdown and leakage tests on a variety of electronic devices at up to 3,000V.
